How to identify which commandLink was clicked? [SOLVED]

[Leigh Taylor]

Hi,

I have recently jumped into the land of jsf and am trying to absorb everything there is. I have run into an issue where i have a number of commandlinks being produced within a dataTable. Each command link calls the same javaScript method. How can i parse information so the javascript method knows which link was clicked?

    
<a4j:form id="OA_Form">
   <rich:dataTable id="ResultsTable" value="#{search.MatchingAddresses}" var="address">
      <h:column>
 <a4j:commandLink id="AddressLabel" value="#{address.addressLabel}" action="updateAddressToMaps()" />
   <h:outputText id="OA_AddressPoint" value="#{address.jsCode}" styleClass="hiddenAddressPoint"></h:outputText>
      </h:column>
   </rich:dataTable>
</a4j:form>

I have no idea who to tackle this issue. I have a hidden variable so i can access all the address matches. Though how do i know which link is clicked?

Thanks

Maybe you could set a hidden field or a variable to a unique value from each link onmousedown.

Or have each link call different javascript, that each in turn call a common javascript function.

I do not know why you are using javascript for an action method instead of server side java code, but I have not used a4j.

Thanks for the reply Bob. As i was generating the links dynamically it wasn't possible to include individual javaScript methods.

I did however work out a solution. The problem being my limited knowledge of binding.

Simply added a binding attribute to the datatable and bound it to the backing bean.

<rich:dataTable id="ResultsTable" binding="#{search.dataTable}" value="#{search.matchingAddresses}" var="address">  

private HtmlDataTable dataTable;
private Address dataItem = new Address();
 
public void zoomToSelectedAddress() {
dataItem = (Address) dataTable.getRowData();
chosenAddress = dataItem.getJsCode();
} 

So the link calls the java method and the method then grabs the row data which i re-injected into my JSP page on reRender.
